IMPROVEMENT IN TUUKING AND PLAITING ATTACHMENT FOB SEWING MACHINES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES Z. MATTISON, of the city of Buffalo, countyof Erie, and State of New York, have invented a new and usefulImprovement in Sewing Machines for Folding or Laying Tucks in Cloth orother material; and I do hereby declare that the following is afull andexact description thereof, reference being bad to the accompanyingdrawings, and to the letters of reference marked thereon.

My invention relates to an attachment for that class of sewing machinesin which a rocker-bar is used to vibrate the needle-carrier, by whichdevice the tucks, folds, or plaits in shirt bosoms or ladies skirts, orany similar article, may he laid and stitched at the same time and ofany desired uniform width.

Figure I is a perspective view of the machine or device attached to asewing machine.

Figure II is a longitudinal elevation of the spring-bar A.

Figure III, a top plan view of same.

Figure IV, a rear view of same. 1

Figure V is a top view of the adjustable rule D; and

Figure VI, a side view of same;

Figure VII is a top plan view of the gauge-plate S; and

Figure VIII, a side view of same.

To enable others skilled in the art to make and use my invention, Iwillproceed to describe its construction and operation.

The spring-bar A, Figs. I, II, III, and IV, consists of a thin metalplate, one end of which is firmly secured by rivets, 1 7' P, and 7-, or'any other suitable manner, to the rigid hook c, which hook is soshapedthat it can be secured by the scre -gito ther'ocker B of a. sewingmachine and attached or detached by the operator, as desired. The otherend of the spring A is rounded and graduated as ascale and marked I, 2,ac. The sliding rule I), Figs. I, V, and VI, is made of metal, one endbeing rounded and the other end having a slot, g, which fits over theraised portion of the gauge-plate S, Figs. I, VII, and VIII, whichgauge-plate is firmly secured to the cloth-plate H of the sewing machineby screws, in 20 fig. I.

The operation of the folding device is as follows: The spring-bar A isfastened to the needle-rocking bar B of a sewingmachine by the set-screwThe cloth or fabric is laid upon the table under the bar A and doubledbackward over itself. The slide D is then so adjusted that its end shalloverlap A the proper distance for the proposed plait or fold. The clothis then laid over the end of D or not, as may be desired, and the seamto be sewed will be in line with the needle-hole a; in the cloth-plateH, as shown in red lines, Fig. I; and when the rock-bar B shall havelifted the needle to its highest position above the cloth-plate thespring-bar will have been correspondingly acted upon, the efiect ofwhich will be that the extreme operative end of A, which lies in thefold of the cloth, and which is held always down and under the slide D,although the remainder of the spring is allowed, by reason of itsyielding character, to be lifted, must be pulled backward, and when thneedle again descends this end of A will again, by reason of the returnmotion of the rocker, and the resilience of the spring, which causes itto resume its straight or nnbent form, he pushed forward to its formerposition to form another portion of the continuous fold, this actionbeing repeated at every movement of the rockingbar. The gauge-plate S isattached to the cloth-plate E by set-screws w 10 and then the slidingrule is secured to the gauge-plate S by the set-screw V, so that therounded end of the rule D projects over the spring-bar, as the fold ortuck is desired to be made. The spring-bar A being firmly connected tothe rockerB of the machine, aiid its outer end, during its backwardmotion, being firmly held down by D, it will be observed that most ifnot all the pressure exerted by it upon the material against the slidingrule D will be Withdrawn, so that it offers no resistance to the foldingmotion of the material or to the feed which now takes place.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-.-

1. The spring-bar A attached tothe rocker of a sewing machine, andoperating as and for the purposes and substantially as described.

2. The adjustable sliding rule D, in connection with the spring-bar Aattached to the locker of the same, lapping-over said spring-bar thewidth of the desired hem, fold, or tuck, and operating in the manner andsubstantially as set forth.

CHARLES Z. MATTISON.
